Step 3: Neutralize. Create a thick paste out of baking soda and water. Apply to the spill to absorb it. Wait 1 or 2 minutes. Wipe up the mixture with paper towel and immediately put the soiled paper towel in the plastic bag. Apply another layer of the baking soda paste.
Causes of Bare Spots in the Lawn. Bare spots in your lawn can be the result of heavy foot traffic (causing soil compaction), drought, disease, chemical burn and weed or insect infestation. Before beginning repairs, you need to determine the source of your problem.
Pesticide, fertilizer or gasoline spills. Spills can cause lawn damage quickly, resulting in yellow or brown spots. Refill spreaders, sprayers and outdoor power equipment carefully. Use a funnel or a no-spill container. You can rake up dry products and collect them for use later. Flood the area with water to dilute.
